Wit t o in a t e 'bi t View h w l appea a t e est itt ei proceeds, the invention resides in the combination and arrangement of parts in the details of construction hereinafter described and claimed, being iindlerstood' that changes in the precise embodiment of e inve t on erein d elexd can b made wlthin the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the device as applied, a portion thereof being broken away.

Fig. 2 is afront view of the device as applied, a portion thereof being shown in sectlon.

Fig, 3 is a longitudinal sectional detail taken on the line 33 of Fig. 2.

Figs. 4 and 5 are cross sections on the respectrve section lines 4 -4c-and 55 of Fig. 1.

Fig. 6 is an end view of the device showing the retaining plug. 7

Fig. 7 is a side elevation of said plug, partly in section.

The device includes an elongated body 1 which may be cast or otherwise manufactured, and which is of tubular form being provided at one side with a longitudinal slot 2 and longitudinal outstanding lips 3 along the edges of said slot. The body 1 is thus of an stantially' ill-shaped cross sec groove 5 adjacent to itsope'n ties wit ts. onnecti g por n nla ged- (1 end i t dyl stloi ed pro rifled with a orna ental knob 4 and the other end of the body is open The body is, R TQYiQBQ W th, an inner t ns e e arcii late end nd 013,- Peti e thes' et 2- A eta nin Plus i atlaptesl t w th he men and at the, edy l nd has. knob. tel menim tins it tQ iateh-the knob,

In applying the device to the radial handles 12 carried by the stems 18 of a gang of valves of the gas range or the like, when said handles "are turned to close the valves, so that the handles all project in the same direction or are in alinement, body or shield 1 is moved lengthwise over the handles, the

slot 2 and lips 3 accompanying the valve stems 13. The plug 6 is then inserted into the open end of the body 1 thereby preventing the removal of the body or shield unless the plug is removed by means of a suitable key. Since the body or shield 1 incloses the handles 12 it prevents said handles from being turned and it is therefore impossible for the valves to be opened accidentally or in tentionally when the device is applied. The device must be moved longitudinally out of engagement as well as into engagement with the handles 12, and the body 1 cannot be pulled off of the handles 12 away from the stems 13, since the handles 12 cannot pass through the .slot 2. The lips 3 materially add to the protection of thehandles 12 by rendering access thereto difficult if not im' possible by Way of the slot 2. To remove the device, the latch 9 is first retracted by a proper key and the plug 6 withdrawn which enables the body 1 to be pulled lengthwise oif of the handles 12 thereby again permitting of the operation of the valves. The device can be quicklyjapplied and removed without requiring tools of any sort, or

screws, wire or other kindred holding or retaining means.

Having thus described What is claimed as new is l. A gang valve lock for gas ranges andthe like, embodying an elongated member constructed to receive and surround a series of handles and having one end open so that it can be moved longitudinally over the handles in succession, said member having a slot for the stems of said handles extend,

adapted to be moved longitudinally onto a series ofvalve handles, and a retaining plug insertible into the open end of said member. 4:. A gang valve lock for gas ranges and the like, embodying a tubular member hav ing an open end and a longitudinal slot and adapted to be moved longitudinally onto a series of valve handles, a retaining plug insertible into the open end of said member and key controlled meansfor holding said plug in place.

6. A gang valve lock for gas ranges and the like, embodying a tubular member having an open end and a longitudinal slot and adapted to he slipped over a series of valve handles, a plug insertible in the open end of said member and having a radial lug to move into said slot, said member having an inner socket adjacent to its open end, and a latchcarriecl by the plug engageable in said socket.
